Malicious code in @antv/g6-plugin-map-view (npm)
The npm account `atool` was compromised and used to publish 631 malicious versions across 314 packages, including @antv/g6-plugin-map-view, in a 22-minute automated burst. Each version injects a preinstall hook executing an obfuscated Bun script that exfiltrates credentials and establishes persistence via CI/CD workflows and system daemons.

- @antv/g6-plugin-map-viewMalicious preinstall hook injected; part of Mini Shai-Hulud campaign
A threat actor compromised the npm account atool and launched the "Mini Shai-Hulud" supply chain attack campaign, publishing 631 malicious versions across 314 npm packages in an automated 22-minute burst on or around July 27, 2026. The @antv/g6-plugin-map-view package was among those compromised.
Each malicious version injects a preinstall hook that executes a 498KB obfuscated Bun script. The script uses the GitHub API as a covert exfiltration channel and commits stolen credentials to attacker-controlled repositories following Dune-themed naming patterns (e.g., harkonnen-melange-742).
Stolen data includes AWS keys, GitHub PATs, npm tokens, GCP service accounts, Azure credentials, Kubernetes service account tokens, SSH keys, Docker auth configs, database connection strings, Stripe keys, and Slack tokens. The attack establishes persistence through CI/CD workflow injection (a GitHub Actions workflow named Run Copilot that dumps all secrets via toJSON(secrets)), AI agent session hooks, and a system daemon named kitty-monitor.
The incident was detected by Amazon Inspector and Google Open Source Security, confirming the malicious code in @antv/g6-plugin-map-view and the broader campaign scope.

Remediation
- Immediately audit and revoke all credentials (AWS keys, GitHub PATs, npm tokens, GCP service accounts, Azure credentials, Kubernetes tokens, SSH keys, Docker configs, database credentials, Stripe keys, Slack tokens) that may have been exposed
- Remove all malicious versions of affected packages from npm; use npm audit to identify installed malicious versions
- Inspect CI/CD workflows for the injected `Run Copilot` workflow and remove it; audit GitHub Actions logs for secret exfiltration
- Search systems for the `kitty-monitor` daemon and remove it; check for unauthorized cron jobs or persistence mechanisms
- Review git commit history for commits to attacker-controlled repositories with Dune-themed names
- Implement package pinning and integrity verification for npm dependencies
- Enable 2FA on npm and GitHub accounts; rotate signing keys
- Monitor for lateral movement and data exfiltration following the incident
